Ohio, a corporation of Sash, Incorporated, Girard, Ohio The presentinvention relates to sash locking devices, more particularly to a devicefor locking the outer sash of a double hung sash construction, and theprincipal object of my invention is to provide new and improved lockingdevices of the character described.

ln prior art double hung storm window constructions suitable latcheshave been provided for holding the inner and outer sashes inrespectivepredetermined positions. However, particularly with metal sashconstructions, it has been possible to unlatch the outer sash from theoutside even though both inner and outer sashes were securely latched inrespective closed positions. Obviously, this has been unsatisfactorysince an intruder could easily gain access to the interior of a houseunless the windows were securely locked.

My invention provides latch means for holding the inner and outer sashesin respective closed positions. Additionally, my invention providesmeans for automatically locking the outer sash in closed position whenthe inner sash is in closed position to prevent the outer sash frombeing unlatched from the outside. This and other advantages will becomeapparent from a study of the following description and from the drawingsappended hereto.

In the drawings accompanying this specification and forming a part ofthis application, there is shown, for purpose of illustration, anembodiment which my invention may assume, and in these drawings:

Figure l is an elevational View of a double hung metal storm sashconstruction embodying my invention,

Figure 2 is an enlarged fragmentary sectional view generallycorresponding to the line 2 2 of Figure 1,

Figure 3 is a reduced size, exploded perspective view of a portion ofthe outer sash illustrated in Figures l and 2,

Figure 4 is a perspective fragmentary view of the inner and outer sashesseparated to better illustrate construction, and

Figure 5 is a reduced size fragmentary sectional view generallycorresponding to the line 5-5 of Figure 2.

As illustrated, my invention is particularly, though not exclusively,adapted for use with double hung storm sash of metallic constructionsince this type of sash, because of space limitations, presents specialproblems in holding and locking the sashes in position.

As best seen in Figure 1, a conventional double hung storm window for ahouse or other structure comprises a frame which provides respectivespaced-apart channels in which an outer sash 11 and an inner sash 12 arerespectively slideable. As will be clearly understood, the storm windowis adapted to overlie a conventional house window (not shown), the frame10 usually being permanently secured to the casing of the house windowby any suitable means.

ln the present embodiment and in the position of parts shown, the outersash 11 comprises an upper member 13, a lower member 14, and sidemembers secured together by any suitable means. The inner sash 12comprises an ICC upper member 16, a lower member 17 and side members 18also secured together by any suitable means.

In the embodiment herein illustrated, the sashes 11, 12, are glazed, anysuitable arrangement being employed to secure a pane of glass Withinrespective sashes. As seen in Figures 2, 3 and 4, a groove 19 adapted toreceive a pane of glass may be formed as shown in each of the membersforming a respective sash. Any suitable means may be employed tosealably secure the glass in grooves 19, for example and as shown inFigure 2, a rubber gasket or the like 20 may be interposed between thesides of the grooves 19 and the glass for this purpose.

As in conventional double hung window constructions and when the stormwindow herein described is closed, the outer sash 11 is positionedadjacent the top of the frame 10 and the inner sash 12 is positionedadjacent the bottom of the frame. In this position of parts and as bestseen in Figure 2, the lower member 14 of the sash 11 and the uppermember 16 of the sash 12 are in overlapping relation but spaced apart bythe respective channels in which the respective sashes are slideable(see also Figure 5). lt will be understood that the inner sash 12 may bemoved in its channel from the closed position shown adjacent the bottomof the frame 10 to a position adjacent the top of the frame. The outersash 11 may also be moved in its channel from the closed position shownadjacent the top of the frame 10 to a position adjacent the bottom ofthe frame.

ln order to close the gap between sashes 11, 12 when they are in closedposition shown in Figure 2, the lower member 14 and the upper member 16are provided with respective ribs 21, 22 which intert as shown toeifectively seal the storm window against drafts.

As best shown in Figures 2 and 3, the means provided for holding theupper sash 11 in the closed position shown or in other preselectedpositions comprises a bolt 23, a member 24 having a transverselyextending portion 25, and a spring 26. The bolt 23 (see Figure 3)comprises a pair of axially aligned, spaced-apart portions 27, 28connected together by a bight 29 for a purpose to appear. The spring 26,member 24, and the portions 27, 28 of the bolt 23 are slideablyreceivable between spaced-apart ribs 30 formed in the member 14. Thebight 29 of the bolt 23 is notched at 32 adjacent portions 27, 28 inorder to provide clearance for certain of the ribs 30, and although thebolt 23 is herein disclosed as being an integral structure, it may, ifdesired, be formed of separate pieces welded or otherwise securedtogether.

A side of the member 14 is notched out at 33 to provide operatingclearance for the portion 25 of the member 24 and the member 14 isfurther cut away at 34 to provide for assembly in a manner to bedisclosed.

At assembly, the spring 26, member 24, and the bolt 23 are adapted to beslid into position between the ribs 30 (in the order illustrated inFigure 3) until the spring abuts a pin 35 or the like (Figure 5) whichextends across the channel 31 between the ribs 30. As illustrated inFigure 3, the member 24 will be so positioned that the transverselyextending portion 25 extends downwardly, ortoward the open mouth of thechannel 31, so as to permit the member 24 to slide between the ribs 30.Movement of the parts 23, 24 against the compression of the spring 26will be continued until the portion 25 of the member 24 is aligned withthe cut-out portion 34 of the member 14.

The member 24 will then be rotated to align the portion 25 with thenotched out portion 33 and the spring 25 will then be permitted to shiftthe member 24 and the bolt 23 to the right until the portion 25 of themember 24 extends into the notched out portion 33 and until the portion28 of the bolt 23 projects beyond the side member 15 of the sash. A pin36 (see Figure 3) may be carried by the member 1,4 so ,that it extendsacross the channel 31 whereby engagement of the bight 29 therewith willprevent unintentional disassembly of the aforementioned part-s.

As shown in Figure 5, an aperture 37 is provided in the frame V1() forreceiving the portion 2S of the bolt 23 when the outer sash 11 is in itsuppermost position. As will be clear, the spring 26 will pres-s againstthe member Z4 which in turn presses against the bolt 23 'to urge thelatter to seat in the aperture 37. When it is desired to shift the sash11, the bight 29 will be grasped by the user and the bolt 23 shiftedagainst the compression of the spring 26 until the bolt is withdrawnfrom the aperture 37.

Means are provided for preventing shifting movement of the bolt 23without first raising the inner sash 12 and in the embodiment disclosed,a laterally extending abutment 3S is provided on the member te of theinner sash 12 adjacent the portion 25 of the member Zd. To preventinterference between the rib 21 and the abutnen't 33, thc rib 21 is cutaway at 21a as shown in Figures 3 and 4. in the position of partsillustrated in Figure 5 wherein each sash is shown in respective closedposition, interengagement between the abutment 33 and the portion Z5 ofthe member 24 will prevent withdrawal of the bolt 23 from the aperture37. ln order to shift the sash 1li, it is tir-st necessary to raise theinner sash 12 so that the abutment 38 is moved through the opening 21aaway from the portionv 25. The bolt may then be withdrawn from itsaperture and the outer `sash 11 positioned as desired.

Although only one lower corner of the outer sash 11 and an adjoiningupper corner of the inner sash 12 have been described and shown indetail, it is to be understood that the opposite lower corner of theouter sash 11 and the adjoining upper corner of the inner sash It). maybe provided with structure identical to that hereinbetore disclosed.Additionally, while means have not been disclosed for locking the innersash rin its closed position, any suitable well-known mechanism may beemployed.

In View of the foregoing it will be apparent to those skilled in the artthat i have accomplishedA at least the principal object of my inventionand it will also be apparent to those skilled in the art that theembodiment herein described may be variously changed and modied, withoutdeparting from the spirit of the invention, and that the invention iscapable of uses and has advantages not herein speciiically described,hence it will be appreciated that the herein disclosed embodiment isillustrative only, and that my invention is not limited thereto.
